Futari wa Pretty Cure / "Together Were Pretty Cure" (Also known as
"We Are Pretty Cure", "Pretty Cure" and more simply "PreCure") is a
childrens anime aimed at girls. It is the story of two girls 
Nagisa and Honoka  who know each other in passing from school but are
merely acquaintances until they are drawn together, whether by chance or
destiny, to become the evil-fighting duo Pretty Cure. In this
team working together is essential  they cannot attack or even transform
into their magical girl forms if they are not together. The show focuses
on friendship, teamwork and first crushes (Nagisa has a crush on Shogo
Fuji-pi Fujimura a friend of Honokas, while Honoka just
might have a crush on Nagisa.)

Powers/Abilities: Heightened agility and superstrength. When together
with Cure White, they can also combine powers to generate magical attacks:

Able to combine forces to fire a beam of energy - Black Thunder, Pretty
Cure Marble Screw  While holding hands Cure Black calls out
Black Thunder and Cure White calls White Thunder
and they are struck by lightening (of the corresponding colour) which they
absorb the energy as they say Pretty Cures beautiful
souls  (said by White)  will crush your dark heart
(said by Black) and together they yell Pretty Cure Marble Screw
and direct a spiral of black and white energy at their enemy. The power of
this attack is relative to the users emotions.

Able to free others from being controlled by evil - Black Pulsar, Pretty
Cure Rainbow Therapy - While holding hands Cure Black calls out Black
Pulsar and Cure White calls White Pulsar and they are both
surrounded by rings of black and white energy which turn into a rainbow coloured
sphere. Cure White says One that is cursed by the Dark Power 
and Cure Black says  we now break the chains that bind you!
and they both yell Pretty Cure Rainbow Therapy and the energy
collected in the rainbow coloured sphere around them flows from them towards
whoever they are targeting and free them of evil influence.

History:
One day Nagisa was watching the evening sky, she made a wish upon a shooting
star that she would have a boyfriend  and she was shocked when a small
glowing meteor landed in her room!

The meteor turned into a mobile-phone-sized device and a deck of strange
pink cards. Inside the device was a creature who called himself Mepple, which
demanded Nagisa took him to see Mipple, his love, who was apparently also
on Earth. He lead her to an amusement park where they found Mipple in the
hands of a girl from Nagisas class  Honoka Yukishiro.

While there they were attacked by the forces of the Dusk Zone and Mipple
and Mepple told them to swipe their Queen Cards in the mobile-like
devices. When they did they automatically joined hands and called out Dual
Aura Wave which transformed Nagisa into Cure Black and Honoka into
Cure White so they could defeat their attackers.

Mepple and Mipple later told the girls that they were guardians from
The Garden of Light, another world under attack from a planet
called The Dusk Zone, which was trying to steal the seven precious
Prism Stones that kept both The Garden of Light and our world (which they
call The Garden of Rainbows) alive. The girls had to fight the
Dusk Zone in order to protect the stones they already had and to retrieve
the stones that the Dusk Zone had stolen.
